Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure.
